2. Messung kohärenter Streulängen durch Kleinwinkelstreuung von Neutronen im Schwerkraft-Refraktometer

Abstract

Using the small angle scattering of neutrons by a “Christiansen-Filter”, a mixture of a grained powder with a liquid, it has been possible to determine the scattering amplitude of powders and liquids with an error within ± 1% or lower. By measurements with Tungsten-powder and mixtures of the liquids C2Cl4and C6H5Cl and with mixtures of heavy and light water we got the scattering amplitudes of the bound atoms: Deuteruma=(6.70 ± 0.05) f and Tungstena=(4.77 ± 0.05) f.
